Web Audio Modem

Geekpr0n: [WayBackWeb Audio Modem

What do you do when you cannot copy text between computers due to lack of internet connectivity? I built a modem using the Web Audio API, allowing data transfer via audio.

It is on github at martme/webaudio-modem: Encode and decode text using the Web Audio API to enable offline data transfer between devices.

There are three demo pages at [WayBackmartinmelhus.com – Web Audio Encoder too:

Delphi Galileo IDE (version 8 and up): Force files to be saved as UTF8 – The Oracle at Delphi

Posted by jpluimers on 2019/07/04

Though formatting mangled the registry key to add, the article is interesting: since 2003 (C# Builder 1), you can force the IDE to always save files as UTF8 which should alleviate a lot of encoding problems.

It beats me why this isn’t the default setting, but below is an example .reg file for Delphi 8 which should be easily transformed to more recent Delphi versions:


Windows Registry Editor Version 5.00
[HKEY_CURRENT_USER\Software\Borland\BDS\2.0\Editor]
"DefaultFileFilter"="Borland.FileFilter.UTF8ToUTF8"

So basically (if formatting is kept), you browse to this key (replace Borland with the company for your specific Delphi version, and replace 2.0 by your IDE version):

HKEY_CURRENT_USER\Software\Borland\BDS\16.0\Editor

Then you add a new string value named DefaultFileFilter with value Borland.FileFilter.UTF8ToUTF8

More background [WayBack] The Oracle at Delphi: More IDE secrets – UTF8 and the Editor

The unmangled registry key (and more tips) was from [WayBackBSC Polska: Hidden possibilities of Delphi 8.

Get the list of HKEY_CURRENT_USER paths for your Delphi version at Update to List-Delphi-Installed-Packages.ps1 shows HKCU/HKLM keys and doesn’t truncated fields any more.

[dcc32 Warning] “W1025 Unsupported language feature: ‘operator explicit'”

Posted by jpluimers on 2019/07/03

If the Delphi compiler throws a Source: "W1025 Unsupported language feature: 'operator explicit'" at you, then it is likely that you forgot this, as per Uwe Raabe:

In the project options set “C/C++ Output file generation” to “Generate DCUs only” to get rid of the warning.

Via: [WayBack] Delphi Community Edition Rant. Just installed Delphi CE from the 3rd attempt. Two times I tried to install all features – both times the installer fell… – Sergey Kasandrov – Google+

Note that the documentation still indicates that W1025 has been documented since at least Delphi 2007 ([WayBack] x1025: Unsupported language feature: ‘%s’) as a C++ header translation issue, and still is ([WayBack] X1025 Unsupported language feature: ‘%s’ (Delphi) – RAD Studio), despite other causes (like "W1025 Unsupported language feature: 'custom attribute'") fail if you have only installed the Delphi personality.

JS developers discover the char code for space is the same ASCII code for all browsers.

Posted by jpluimers on 2019/07/03

Somewhere in 2013, JavaScript developers found out the char code for space is the same ASCII code for all browsers at [WayBackJavascript Char Codes (Key Codes) – Cambia Research

An interactive javascript key code reference for javascript developers. Includes an interative text box where you can type a key and see it’s code along with a complete lookup table.

This contrary to EBCDIC, where space can be character code 40 and 41, but not at the same time (by [WayBack] Armin Kunaschik at[WayBack] Oh mein Gott – Kristian Köhntopp – Google+).
